Abstract

The present invention provides a call method and related products. The method includes the following steps: sending a call request to a first network device; receiving a radio resource control RRC connection release message corresponding to the call request, and the RRC connection release message includes : multiple 2G frequency points; when it is determined that the call request is a cross-area call, at least one abnormal frequency point is obtained by detecting the multiple 2G frequency points, and the at least one abnormal frequency point is automatically blocked; select from the remaining frequency points One frequency receives the call control setup CC_SETUP message of the second network device to implement the access of the call request. The technical solution provided by the invention has the advantages of improving the success rate of access and improving user experience.

Description

technical field [0001] The invention relates to the technical field of terminal equipment, in particular to a calling method and related products. Background technique [0002] The Long Term Evolution (English: Long Term Evolution, LTE) network is a fully packet-switched network. For the LTE network, the voice service will remain an indispensable and important service for a long time. In order to ensure the smooth development of high-quality voice services on the LTE network, various standard organizations have actively studied and proposed a variety of voice service solutions. One possible form is that the terminal can use circuit switched fallback (English: Circuit Switched Fallback, CSFB) technology to achieve voice services. In the LTE network, CSFB technology may have call failure, which affects user experience. Contents of the invention [0003] The embodiment of the present invention provides a calling method and related products, which can improve the calling suc...
